Application: kate (3.4.2)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
This has probably happened to me over 20 times in kate and while I can't reduplicate it on the fly, I have a good idea when it's going to happen.  Here are the conditions that cause this crash:

1. This only happens with kate running on Linux.  It's never happened with kate running in Windows.

2. The crash only occurs after I've been using kate for several hours.

3. This is always triggered when I'm editing bash scripts.  More specifically, whenever I type a double-quote followed by some text, kate has the horribly annoying behavior of automatically moving the double-quote *after* the text.  For example, if I type something like "$foo", kate always transposes the double-quote with the very next character I type.  The kate crashes occur right after this.

As a work-around, I've gotten into the habit of quitting out of kate and re-starting it every hour or so but this of course is very disruptive.

The crash can be reproduced some of the time.
